Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Damn.

As if risk of tick-borne encephalitis (which can be vaccinated against) wasn't enough, now there apparently is a risk of mosquito-borne encephalitis. And this particular virus has killed one person whose work I valued very much (alongside thousands of others during decades, of course).

It spreads sporadically however, and doesn't transmit between humans in easy ways - so it has been poorly researched and there is no vaccine. I hope there will be one soon enough. Creating vaccines has become considerably easier thanks to the rush to create COVID vaccines. Validating them without emergency regulations and special permissions is a long process however.

Edit: a vaccine against this stuff is likely close enough. And if there is a vaccine, there is soon also an antibody product which can be used to save an unvaccinated person if it gets severe.

As of 2019, six vaccines had progressed to human trials but none had been licensed in the United States. Only the two live attenuated vaccines produced strong immunity after a single dose.[98]
